项目摘要

This research project Parallel and Explicit Time Integration Methods for the Simulation of Eddy Current Problems continues the work started in a forerunner project funded by the DFG grant. The objective of this project is to develop efficient parallel algorithms for the simulation of eddy current problems that are well suited for current heterogeneous massively parallel computer architectures. Since the parallelization of conventional implicit and the recently developed (semi-)explicit time integration methods for magneto-quasistatic problems might not scale well beyond a specific number of cores, also the application of parallel-in-time methods like Multiple Shooting or Parareal is proposed. These methods show new additional potential for an efficient parallelization along the time axes.The newly developed algorithms aim to allow for a faster computation of magnetic fields e.g. in three-dimensional high-resolution models of transformers, actuators and electric machines than established methods. This enables optimization and uncertainty quantification and is especially relevant e.g. in the design process of new inverter-fed electric machines for electric vehicles. Within the previously funded research projects the development of parallel and (semi-)explicit time integration methods set the foundations for the further acceleration of the magnetic field simulations and an even extended use of GPU acceleration. Within this following-up research project, these recently developed algorithms are to be improved and further acceleration of high-resolution three-dimensional magnetic field simulations models is to be achieved by additionally adopting and extending the Parareal methodology.

这个研究项目的并行和显式时间积分方法的涡流问题的模拟继续在DFG赠款资助的先导项目开始的工作。这个项目的目标是开发高效的并行算法，涡流问题的模拟，非常适合当前异构大规模并行计算机架构。由于磁准静态问题的传统隐式和最近开发的（半）显式时间积分方法的并行化可能无法扩展到特定数量的核心之外，因此还提出了时间并行方法（如多次射击或Parareal）的应用。这些方法显示了新的额外的潜力，一个有效的并行化沿着的时间axes.The新开发的算法的目的是允许更快的计算磁场，例如在三维高分辨率模型的变压器，致动器和电机比建立的方法。这使得优化和不确定性量化成为可能，尤其适用于电动汽车的新型逆变器供电电机的设计过程。在之前资助的研究项目中，并行和（半）显式时间积分方法的开发为进一步加速磁场模拟甚至扩展使用GPU加速奠定了基础。在这个后续研究项目中，这些最近开发的算法将得到改进，并通过额外采用和扩展Parareal方法来进一步加速高分辨率三维磁场模拟模型。
